IMO, fpc version is important. fpc-3.0.4 from distro crashes, fpc-3.0.4 
built via fpcupdeluxe works, fpc-3.2.0beta works (because it's built via 
fpcupdeluxe ? ).
Also, KDE Plasma have bug somewhere in KioCore which triggers on qt app 
close - for this, I must test pure Qt5 application to see what's going 
on. In this case Qt4 apps are crashing too.
How to reproduce such crash: simple form with TOpenDialog or 
TSaveDialog, start your project, open dialog, close dialog, close app 
and you'll segfaulted.
